With the ground area of 3.766 hectares, the treatment capacity of Jinan East Station Wastewater Treatment Plant is 100,000 m³/d. The plant started its duty since 2020, is the first large-scale underground wastewater treatment plant in Jinan City.

The increasingly tighter government regulations on the discharge of industrial wastewater due to the environmental effect make ZLD necessary when water is scarce or the local water bodies are protected by law. In the last decades though, there has been an effort from the water treatment industry to revolutionize the high water recovery and ZLD technologies. Membrane technology has become one of the technologies that involved.

The source of hospital wastewater contains a variety of bacteria, viruses, parasitic ovum, which is mainly composed of infectious bacteria wastewater, radioactive wastewater, wastewater with bacteria, and general domestic wastewater. In recent years, the membrane bioreactor (MBR) process, which combines the secondary biochemical treatment and tertiary advanced treatment, has achieved good results in the treatment of hospital wastewater.

MBR is a wastewater treatment process integrating biochemical treatment and membrane filtration treatment, which has the technical characteristics of stable, controllable and good effluent quality. During the operation of the process, most of the pollutants can be removed in the biochemical treatmen

With the increasingly strict standards of urban sewage treatment and discharge, many sewage treatment plants are facing the challenge of upgrading. Submerged MBR has become a popular technology for the applications of municipal sewage treatment plant construction, reconstruction and decentralized wastewater treatment.

Project to upgrade landfill leachate treatment facility for Qixia domestic waste transfer station, Nanjing, has been completed and accepted recently, which adds another brilliant achievement for Kaimitech in the business of landfill leachate treatment.

Membrane separation technology has the advantages of low energy consumption, high efficiency, stable operation and good effluent water quality. It has gradually become the main development direction of leachate treatment technology.

Kaimi ultrafiltration tubular membrane systems for fruit and vegetable juice are widely applied to more than 200 juice and vegetable juice manufacturers for clarification.

Apply tubular membrane to juice clarification can easily remove the bacteria, pectin,crude protein,etc. which may advance the degeneration of the juice products. With the aromatic ingredients and nutrients retained, the product quality is much better. Comparing with conventional clarification methods, Tubular memebrane ultrafilteration clarifaiction process has been gradually showing its advantages. Kaimitech made UFstarTM System is a great example for tubular membrane jucie clarication application.

High packing density tubular membrane is the core technology for Kaimitech's External Tubular Membrane Bioreactor (TMBR) system, which is widely recognized for its characteristics of strong durability, antifouling and easy operation and maintenance. It is widely used in landfill leachate treatment, oilfield produced water reuse, ink wastewater treatment, acid/alkali wastewater recovery, brine refining treatment and other industries.

Ceramic membrane is the precision casting porous ceramic filter. Driven by TransMembrane Pressure, runs as Cross Flow FIltration mode, for separation, concentration and purification. It is made of Aluminia, Titania or Zirconia oxide.     

The membrane products are for Microfiltration, Ultrafiltration, Nanofiltration. We devote to supply integrated solution of membrane products for wastewater treatment, and other liquid separation, concentration, clarification.

Extract gelatin from fish, bone,skin etc., then use membrane technology to extract gelatin and concentrate gelatin. membrane technology applied in gelatin extraction and concentration are ultrafiltration membrane and nanofiltration membrane. Membrane technology is high efficiency and energy saving.

Kaimi held lecture for engineers, technicians, R & D researchers and process development engineers, about Landfill leachate treatment.

Kaimi tubular ultra-filtration tubular membrane is made of modified PES and lined in its supporting steel tube. The most distinctive advantage is its tolerance to 15% H2SO4, 20% NaOH and pH 0-14. Anti-polluting and anti-scaling also matters for its competitiveness with 12.5mm wide channel.

For large membrane area, wide flow channel and resist sewage blocking, it’s widely applied in landfill leachate treatment.  Nowadays, MBR+N F/RO process for landfill leachate treatment.
