Its research field covers various cutting-edge technologies of water treatment, and provides high-quality products and efficient proce-ss solutions to nearly 1000 industrial water treatment customers in 50 countries around the world
R & D Experiment Center
The R & D experimental center was established in 2005 and has a history of 15 years.The experimental center has various experimental instruments, which can detect most of the water quality and provide timely and fast services to solve customers' practical problems.
The water quality analysis items that can be completed by the R & D experimental center include: SDI value, oil content, COD, ammonia nitrogen, total nitrogen, total phosphorus, pH, potassium ion, calcium ion, magnesium ion, sulfate, chloride ion, acidity, alkalinity, conductivity, TDS, etc;The filter membrane analysis items that can be completed include: maximum pore diameter, average pore diameter, filtration accuracy, etc.
The R & D experimental center also has various membrane material synthesis simulation platforms, various membrane material performance evaluation equipment and solid-liquid separation experimental testing;In addition, filter element test line and SDI instrument test line are built.
Experimental center instruments and equipment

It is suitable for water analysis and BOD determination. It is a special constant temperature equipment for the cultivation and preservation of bacteria, molds and microorganisms. It can be used for the determination of microorganisms in water samples and filter products.。

It is applicable to various chemical and physical experiments that need to work at low temperature, and is used to maintain a constant low temperature in the test process.

It is mainly used for concentration, crystallization, drying, separation and solvent recovery.It is especially suitable for the concentration and purification of biological products that are easy to decompose and denatured at high temperature.

It is used for constant temperature heating of rotary evaporator with excellent temperature control performance to ensure the constant temperature environment in the test process.
。

Test the bubble point pressure of the sample.Bubble point tester, also known as integrity tester, is used to test the accuracy and integrity of filter elements and filter materials.

The oil content in sample water was measured by infrared spectrophotometry.

intelligent digestio-n instrument
The digestion pretreatment of COD, total nitrogen, total phosphorus and other water samples is carried out, the heating temperature is set and displayed digitally, and the heating temperature is automatically controlled.

It can analyze and test conductivity, resistivity, TDS and salinity.
