Industrial waste water is commonly re-used and recycled nowadays with UF+RO processes. Large capacity, high TDS, high hardness and refractory organics are the main characteristics of industrial waste water. High recovery rates to minimize the concentrate discharged or even zero discharge is demanded by environmental protection laws and regulations in most countries, especially in some developing countries where water resources are scarce, such as China. With significant design and project management experience in waste water treatment based on membrane technologies, Tenche has developed a series of treatment processes for industrial waste water re-use and recycling, in order to minimize the concentrate to attain a high recovery rate.
OCRO membrane, with superior anti-fouling and scaling ability and high operating pressure, are highly suitable for industrial waste water in the area of re-use and recycling. Tenche’s typical processes for industry waste water re-use are given below (based on feed water TDS: 5,000～15,000 mg/L);
The unique advantages of this process is as follows:
1)Low energy cost 2)High recovery rate up to 95% 3)Long membrane life 4)Convenient Operating and Maintenance 5)Small system floor space;
