A hydraulic manifold is a manifold that regulates fluid flow between pumps and actuators and other components in a hydraulic system. It is like a switchboard in an electrical circuit because it lets the operator control how much fluid flows between which components of a hydraulic machinery. For example, in a backhoe loader a manifold turns on or shuts off or diverts flow to the telescopic arms of the front bucket and the back bucket. The manifold is connected to the levers in the operator's cabin which the operator uses to achieve the desired manifold behaviour.
A manifold is composed of assorted hydraulic valves connected to each other. It is the various combinations of states of these valves that allow complex control behaviour using a manifold.

The core technology of the reused water and upgrading project adopted Tsinghua University's scientific and technological breakthroughs in bio-ceramic contact oxidation technology and Changzhou Aisite Electrosorption patented technology. The 10,000 tons/day water reused after the electric adsorption is upgraded meets the chemical production process water standard and can be used as process water, boiler supplemental water, and the like. The electro-adsorption device can increase the suspended solids from 10 mg/L to 3 mg/L, the turbidity from 10 NTU to 1 NTU, the ammonia nitrogen from 10 mg/L to 5 mg/L, and the CODCr from 25 mg/L to 10 mg/L. Rise. After the plant is put into operation, it can reduce the emission of CODCr9293 tons, BOD54,454 tons and ammonia nitrogen, 1560 tons per year for Taihua, effectively improving the quality of regional water bodies, and at the same time, it will help ease the pressure of water supply in the severely water-scarce city of Taiyuan.
The process is original and internationally advanced. It has features such as simple pretreatment, low power consumption and operating costs, long equipment life, simple operation and management, and wide application range. The salt removal rate is greater than 75%, and the water recovery rate is up to Above 75%, the electricity consumption is 1 kWh/ton water, and the cost of water production is low. The cost per ton of high quality reclaimed water is 1.95 yuan (the cost of fresh water for Taihua Industry is 3.4 yuan/ton).
It is understood that due to the inadequacy of industrial wastewater treatment, the country’s chemical companies have lost 2 trillion cubic meters of industrial wastewater every year, which has not only wasted precious water resources, but also caused serious pollution to the environment.
On July 27th, the first domestic large-scale sewage treatment 10,000 tons/day water reuse upgrading project - 10,000-ton electric adsorption device was completed and put into production at the Taiyuan Chemical Industry Group Co., Ltd. water plant. The technology has the promotion value in the utilization of sewage in the chemical industry and is expected to create an annual profit of 8.8 million yuan for Taihua.
