Water Recycling Unit
Applauded across the industry as leading firm, we are engaged in precisely manufacturing the gamut of Water Recycling Unit. These units are technically assembled by our professionals using quality assured material and functional components. Technically sound, our units are used for recycling the wastewater coming from car washing activities. Further, the stock of Water Recycling Unit finds its applicability across many large car washing industries.
- Easy to operate
- Long service life
- High operational fluency
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. (This will depend on the organic matter found in the Influent and may not be essentially required).
The quartzite filtering station and following activated carbon adsorption complete the purification process of the wash water. The quartzite-filtering phase removes any sedimentable or suspended matters from the water that escaped the previous treatment phases. The activated carbon adsorption section eliminates the residue organic matters such as oils, detergents and solvents. The plant is not designed to deal with substantial quantities of free oil. The water, following the aforesaid biophysical treatment, is suitable to be sent back to the bus / car wash system and to be drained as it will meet the limits specified by local pollution control committee.
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).
Since no chemicals are used the problem of maintaining correct chemical balances, checking their levels and cost of chemicals are avoided.
The system has been designed based on the dirty wash water quantity and in relation to pollutants in the water.
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. Therefore no particular care and maintenance is required. It will be sufficient to simply check the efficiency of the filters on the odd occasion. Pressure gauge is provided to determine backwashing frequency of quartzite filter. It is recommended that Filter columns may be washed once in a day or at a frequency as required.
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.
An underground tank of 12-m3 capacity for collection of the dirty water is provided. This is divided into 3 tanks V1, V2, V3 of 4m3 each. The tank provides for 4 hours settling time.
Other models having higher capacities of treatment of waste wash water are available.
