To simplify the explanation, the different phases are divided as follows:

1. COLLECTION OF PROCESSING WATER

• Dirty water coming from the factory flows through the channels and is collected in the Collection Tank
• An initial filter, in a small pit just before the collection tank, is provided to stop possible big parts and extraneous material from entering.
• In the bottom of the collection tank operates a fluidization ring made with several water jets fed by the primary pump (see PUMP STATION). Its function is to prevent the sludge from collecting in the corners and the bottom of the tank

2. PUMP STATION

• Two identical pumps operate with daily alternate cycles to take the water from the tank and to send it through the treatment system.
• Each pump is installed with its own non-return valve, filter and anti-cavitation system fitted on its intake pipe
• A small part of the pumped flow, returns into the collection tank to supply the fluidization ring
• All the DTP system is filled of water and it operates completely under the pressure given by the initial pump. This is maintained right through to the processing machines.
• Several visual and electronic pressure meters control the pumps’ work and provide information to the main CPU.

3. DECONCENTRATOR

• This is the main tank where the physical – dynamic separation, between water and glass mud, occurs
• The dirty water is pumped into a small hole in the bottom part of the tank and then flows out from the top of the tank almost completely cleaned.
• Inside the Deconcentrator there is a particular fixed circuit, that forces different speeds in the water flow, which achieves the separation of the suspended solids and particles of glass from the main body of water
• The glass mud remains automatically in two chambers in the lower part of the Deconcentrator
• The clean water, at the end of this circuit, flows out from the top of the tank
• The glass mud is regularly disposed off from the Deconcentrator by the programmed operation of 2 pneumatic valves  (see SLUDGE DISPOSAL)
• The sequence of the 2 pneumatic valves operation is at scheduled times controlled by the data coming from the flow controls.

4. MICRO FILTRATION

• After the exit from the Deconcentrator the water is filtered (still pushed by the initial pumps’ pressure) through a traditional multi-mineral filter
• The quality of this filtration is a result of this MICRO FILTRATION. Residual solids particles’ dimensions are less than 10 microns and total ppm remained is less than 10 mg/lt. The water quality is clear.(LIMPID)
• After filtration the clean water flows directly to the processing machines through an existing distribution ring (always with the pressure generated by the initial pump)
• This mineral filter is self-cleaning on a daily cycle. This operation takes about 35/40 minutes and is normally foreseen during the night or at a selectable convenient time (it is an automatic-start operation according with the settings and can take place also during the week-end or holidays)
• The mineral filter combination of circuits allows in automatic-mode the followings: WORK – SELFWASHING – RINSE – FILTER BYPASS (this last one is only in safety mode). The rinse (back-flushing) water is dumped to waste.
• Inside the filter, 2 iron plates with dozens of holes on each. Each hole is fitted with an ejector, which holds the minerals inside the unit and lets the water pass through, both during the WORK and the SELFWASH and RINSE cycles.
• The dirty water discharged during the self-washing cycle returns into the initial collection tank.

5. SLUDGE DISPOSAL (from the Deconcentrator)

• The Deconcentrator’s two sludge discharge lines with water which is heavy charged with glass mud, leads to a “Big-Bag” filtration station.
• Two disposable big bags filter the water, keeping inside the bag the solids (sludge) and filtering the residual water into a base tank/basin and from there back to the initial collection tank.
• The removal of the big bag, when filled with solid sludge, is made with a simple forklift and replaced with a new one.

5. ELECTRIC PANEL AND CONTROLS

• All functions are selectable in a Manual or Automatic mode; the normal use is in Automatic
• The control cabinet is fitted with all the switches enabling these options and for each single function
• A PLC, with touch screen, enables the management of all parameters and controls of the system, divided into several user menus
• An inverter manages the pump/s RPM and power consumption to ensure the right power is supplied for the required water flow
• The main control board registers all the warnings or alarms, and a combination of warning lights and/or sounds start when a situation occurs. (customizable)
• The system includes a connection board to enable the Remote Control for after sale assistance or (optionally) for the Remote Staff Control of the system

6. GENERAL INFORMATION

• The DTP supplies, in one single water outlet, all its nominal capacity of water, all treated and cleaned with the mentioned quality parameters (see MICRO FILTRATION)
• It is suitable for 23.5 hours work on a 24 cycle. A 24/24 (continuous operation) module is optional if required
• The system is available in different sizes from 12 to 250 m3/hour (see table joined) to satisfy all requirements, from the small laboratory to the giants of glass processing.

ADVANTAGES:

• Limpid water suitable for the spindles of the CNCs and for the washing machines
• Totally automatic functioning, operator is not needed
• Remote control both for manufacturer’s assistance and for the user
• Elimination of the water tanks under the machines with the creation of direct drains in the ducts
• Elimination of the pumps on the machines
• Savings of 45/65% in electrical costs thanks to the elimination of the pumps of individual machines
• No maintenance due to deposits on machines, pools, channels, collection tank and pipes for sending water to the machines
• No use of chemical flocculants
• Several depuration testing points along the internal phases of the circuit (3 from the inside of the deconcentrator and 2 from the filter)
• Possibility of modular expansion of the system in a simple and economical way
• Possibility of optional modules, for instance 24/24 or creation of any interface for automated production lines

SYSTEM COMPONENTS:

• Collection pool for dirty water
• Fluidization system and pumps manifolds
• Suction pumps

So it is a standard DTP that, for size and accessibility reasons, has been simplified and is suitable for plants with a lesser water flow.

The DTPs is particularly suitable for the cleaning of water coming from single machines or groups of machines that share the dirty water collection tank, without giving up the many advantages offered by the high technology and performances of the DTP system.

The characteristics of the DTPs project makes it easy to install and is suitable for many uses. Like the whole DTP range, the management is completely automated with no need for an operator.

The DTPs can be expanded with different modules that make it a flexible solution, meeting the different installation and service requirements of the Customer and allowing a direct connection to the CNC and washing machines lines, always under pressure.

The DGS finds application both on ID and DTP plants.

ADVANTAGES:

• Water with no residuals of glass
• No need of dedicated operator
• Automatic system
• Reduced spaces occupied
• Dehydrated and compacted residuals
• Saving on maintenance of working machines
• Customer-installable system
• No discharge in sewerage
• Low costs

The plant has been projected according to the following operating cycle:

– Transfer of waters to be treated to an underground collecting pool

– Sludges dehydration with recovery of clean waters

Thanks to this feature the installations DEM are particularly suitable for creating closed circuits of demineralized water that is constantly treated passing through the plant. A warning LED will indicate the state of saturation of resins which, once exhausted will be replaced in a simple operation which does not require specialized technical personnel.

The plants DEM are normally used in washing machines to get a perfect absence of residues from surfaces.

The OSM produces demineralized water, to programmable values, normally used in washing machines to get a perfect absence of residues from the surfaces of the glasses.

The OSM may serve a single washing machine, or a group of the washing machines or complete industrial plants, being sized from 100 liters / hour until reaching volumes from 20,000 liters/hour and even more with specific customized project.

It ‘a system  dedicated to the treatment of water contaminated by paints normally from the cleaning of the frames of the press. It allows the creation of a closed circuit through recovery of the dirty water and the accumulation of clean water for subsequent reuse.
