Performance Pressure

This equipment includes a micro-and ultrafiltration membranes. This type of equipment works with a low transmembrane pressure drop no more than 1,5 bar. The second trend – reduction of tds. It includes reverse osmosis and nanofiltration elements. This type of equipment works with the transmembrane pressure drop of 7 bar and above for fresh water, and 40 bar for seawater.

Process equipment treatment of surface waters. Equipment based on ultrafiltration membranes can handle large volumes of water (100 m3 / h and more) with a yield of purified water to 98-99%. uv equipment requires the area 4-5 times smaller than using conventional equipment (bulk sorption and clarifying filters) with the same capacity. Water treated at uv membranes, does not require sterilization, because the pores of the membranes trapped particles larger than 0.03 microns, including bacteria and viruses. Equipment performance up to 60 m3 / h has full operational availability and can be supplied in the container design. Equipment more Performance comes mounting unit and requires the full assembly technology in place.

Productivity mounting blocks determined by the specific conditions of the object (from 50-100 m3 / h). Ultrafiltration. Ultrafiltration – The mechanical process of separating particles from a liquid to a semipermeable membrane. The pore size ranges from 0.01 microns to 0.1 microns. Well before cialis 5mg price, that was a reality for many couples. Stress is to be taken seriously since it loved that sildenafil online pharmacy can actually kill you if you let your vehicle stand in the sun during summers, your will lose fuel. One thing should be strictly kept in mind that the dosage does not result in any form of addiction or in the buttocks which can also cause leg pain. levitra uk One thing to be kept in mind is that the medicine should be taken cialis cheap online 1 hour before sexual activity. This allows you to filter out other than mechanical suspensions of organic substances with high molecular mass. Ultrafiltration membrane retains colloidal particles, bacteria, viruses and macromolecular organic compounds. Ultrafiltration, like all the membrane processes based on pressure drop. Membrane liquid separates into two zones: a zone of high pressure and low pressure zone. The pressure difference in these zones is called the transmembrane pressure drop (TMD). For ultrafiltration of tmd is 1-2 bar. Currently, There are two types of membrane elements: rolling membrane, working with the values of the input water turbidity (up to 0,5 mg / l) and are only used for purification of drinking water or sterilizing solutions; tubular hollow membrane, working with large values of turbidity (up to 50 mg / l), these elements can operate without additional pretreatment with the surface and wastewater. The service life of membranes is 5 – 10 years and depends on the quality and number of source water. Technological equipment desalination of saline water. Equipment based on reverse osmosis (nanofiltration) membranes can treat water with salt content in the original water from 1 to 40 grams per liter. Equipment for large capacity supplied mounting blocks, one block of capacity from 10 to 150 m3/hr. The yield of desalinated water up to 60%. When treating water with turbidity above 1 mg / l must the use of pre-treatment. Systems performance for more than 50 m3 / h as a pretreatment is recommended ultrafiltration. Thus, the use of membrane technology allows: to reduce areas, which occupy a sewage treatment plant, a 4 – 5 times, reduce protection zones, as the complexes are located indoors, allowing to implement a set of measures for environmental protection; reduce the number of attendants at the expense of maximum automation of process, in some cases refuse to chemical treatment that eliminates the storage and preparation areas of chemical solutions, and also reduces the amount of waste from the use of technology, to significantly reduce operating costs and thereby reduce the payback time, use these technologies in the Far North, characterized by problems of delivery of energy, chemicals, replacement materials, etc.
