ZERO DISCHARGE UNITS - NO DISCHARGE IN DRAINS - RECYCLE WASTE WATER
The system has been especially designed, incorporating the latest technology, and manufactured to Biophysically(without use of chemicals) treat wash water coming from car washing activity being carried out either manually / or by Automatic Vehicle Washing Machine.
There are 2 types of plants:
|Minimum Order Quantity||1 Unit|
|Automation Grade||Fully Automatic|
|Installation Type||Containerized Plug & Play|
|Water Source||Industrial Wastewater|
The system has been especially designed and manufactured to biophysically (without use of chemicals) treat wash water coming from car washing activity being carried out either manually / or by Automatic Vehicle Washing Machine.
In order to preserve the quality of the water sent back to the car wash system, air is blown into the storage tank of water to be treated and that of purified water. The purpose of the aeration is to prevent anaerobic process to set-in that creates degradation phenomena with the formation of bad and unpleasant odours.
The quartzite filtering station and following activated carbon adsorption completethe purification process of the wash water.
The plant is not designed to deal with substantial quantities of free oil.
The biophysical systems are comparatively advantageous since there is no recurring consumption of chemical products and no sludge is produced (both present in the chemical- physical type purification system).
The system consists of 2 filtering columns one each of quartzite and activated carbon mounted on common base plate with sludge pump. The pump for backwashing and pump for transferring the recycled water to the main wash water tank is also mounted on the base. The operation is controlled manually / automatically by means of a control panel.
The supply flow rate of the system has been set at 2.5 cubic meter/hour max.
The system is self-run by level switches that will pilot the starting and stopping of the electric pumps. It is recommended that Filter columns may be washed once in a day or at a frequency as required.3. WASTE WATER CHARACTERISTICS
The wastewater to be treated comes from the external washing of vehicles. The water is characterised by the presence of mineral oils, surface-active agents, solid suspended matter and solid sedimentable matters.
The detergents used in the individual pre-washing phases such as shampoo and wax are the so-called “ecological car/bus wash” products which are largely neutral in nature and biodegradable.
Models having lesser/higher capacities of treatment of waste wash water are available.
4. TREATMENT CYCLE
The treatment cycle consists of:
b) Oil separation
c) Biological oxidation (wherever required)
d) Purification systems
i) Quartz filtering
ii) Filtering through adsorption material
e) Treated Water Tank
g) Recycling the treated water.
