CBS - Band Filter System
The CBS Wastewater Treatment Systems use Ctech's PolyClay technology to clarify spent solutions, emulsions and industrial effluent. The CBS treatment system provides batch treatment process to meet specific waste removal needs, reduce labour cost, and minimise space needed for placement. Standard systems have a throughput capacity of up to 3 m3 per hour, with treatment tank sizes ranging from 350 litres to 1500 litres for optimum efficiency and economy.CBS systems are manufactured in Stainless Steel and Polyethylene. The CBS system can be provided as a manual or automated system.
Treatment Tank
Treatment tanks are of conical-shape design with decant connections located on the bottom side of the tank. Mixers are installed in the tanks, mounted on a support bridge.
PolyClay Dosing Feeder
Feeders are available with a 45 litre hopper for manual filling using 25 kg bags of PolyClay.
Mixers
On all CBS systems, mixers have been selected to provide optimum mixing during the addition of PolyClay chemicals and during the treatment process.
Bandfilter Unit
A trough shaped bandfilter of stainless steel wire mesh that permits dewatering of sludge from the treatment tank. The band filter is driven by a geared electric motor regulated by a level control switch.
Collection Tank
Located beneath the band filter and equipped with a 21/2" discharge line for gravity feed to the sewer.
Control Panel
The CBS system can be operated in manual or manual/automatic mode, control panels to meet specific site requirements can also be supplied. Manual control panels are supplied with pushbuttons and manually set timers. Automatic/ Manual control panels are supplied with a manual/automatic selector switch push buttons. In the automatic mode the treatment process is automatically executed.
CBS SYSTEM KEY FACTS
The CBS system is a skid mounted system, pre-wired and tested for trouble-free operation from day one. The key features are:- Up to 1500 liter per batch treatment capacity.
- Materials used for the equipment are chosen for its durability: HDPE or Stainless Steel for the tank and Stainless Steel for the band filter.
- Treated water and sludge is run through a band filter assembly for maximum quality.
- System produces 20 to 35 percent dry solids cake on average.
- Optional automation of the batch via PLC.
- All controls are centrally located for ease of operation. Complete manual overrides.
- Easy to operate, no highly skilled operators required.
Typical Treatment Process with PolyClay and CBS Treatment System
 |
1. The reaction vessel is filled with wastewater. After filling, the mixer is started and the PolyClay Reactive separating agent is added to the mixing wastewater. During this time, a large floc can be observed forming in the water. The mixing continues for 5 - 10 minutes. The mixer is then stopped, and the floc is allowed to settle. After 5 minutes of settling, the mixer is turned on again shortly. The treatment process is than finished. |
 |
2. The treated, clean water and the sludge is than pumped onto the filter media where it dewaters by gravity. A level detection determines when the sludge builds up too high on the filter media and automatically advances the filter media to ensure even dewatering. The sludge and filter media then fall into a disposal container. |
