Sand water separator

Solid-liquid separator

Solar aerator

The solar aerator uses solar energy as the direct driving force for the operation of the equipment. It is equipped with a unique rotary-cut lifting aeration impeller. Through the rotation and lifting effect of the impeller, the oxygen-deficient water at the bottom is transferred to the surface of the water body to mix with the oxygen-rich water on the surface; the surface layer is rich in oxygen. Water diffuses horizontally and vertically through centrifugal rotation into the anoxic zone at the bottom.This achieves the triple functions of water body destratification, oxygenation, and vertical and horizontal circulation and exchange, transferring supersaturated dissolved oxygen water from the surface layer to the bottom layer of the water body, increasing dissolved oxygen in the bottom water body, eliminating natural stratification, and improving the self-purification ability of the water body.

Mobile aerator

The water flow generated by the submersible pump passes through the nozzle to form a high-speed water flow. A negative pressure is formed around the nozzle to suck in air. It mixes with the water flow through the mixing chamber and generates a water-air mixed flow in the trumpet-shaped diffusion tube. It is sprayed out at high speed and entrained with many bubbles. It vortexes and stirs in waters of larger area and depth to complete aeration, and its shaft power does not change with changes in submersion depth, and the air intake volume can be adjusted.Because of this, jet aerators can be used in pools with large water level changes.

Sewage pump

A sewage pump is a pump product in which the pump and motor are integrated and work underwater simultaneously. Compared with general horizontal pumps or vertical sewage pumps, the sewage pump has a compact structure and a small footprint.It is easy to install and maintain. Large sewage pumps are generally equipped with automatic coupling devices for automatic installation. Installation and maintenance are very convenient.Long continuous operation time.Because the pump and the motor are coaxial, the shaft is short, and the rotating parts are light in weight, the load on the bearings (radial direction) is relatively small, and the service life of the sewage pump is much longer than that of ordinary pumps.There are no problems such as cavitation damage and water diversion.Especially the latter point brings great convenience to the operator.The vibration and noise are small, the temperature rise of the motor is low, and there is no pollution to the environment.

Sand water separator

It is used in the grit settling tank of sewage treatment plants to separate the sand and water mixture discharged from the sedimentation tank.

Rotary rake mechanical grid decontamination machine

The GSHP type back-grid horizontal decontamination machine is used in the inlet channels (#) of urban sewage treatment plants, water plants, rainwater systems, etc. It can self-test and remove floating objects in the water to ensure the normal operation of the next process.

Solid-liquid separator

Environmental protection The RKSF vibrating solid-liquid separator, successfully developed according to the needs of the breeding industry, is a new type of environmentally friendly equipment suitable for separating livestock and poultry manure sewage liquid.

Project Case

The company has now formed the design and manufacturing capabilities of special water treatment equipment and pump products in fifteen series with nearly a thousand specifications. The products are sold all over the country and exported to Southeast Asia and other regions, playing an active role in promoting national environmental governance.

How to choose a suitable mud scraper?

The mud scraper is a commonly used cleaning equipment. Its existence reduces people's physical labor and helps us clean the floor quickly.However, if we do not maintain the mud scraper correctly, its service life will be greatly shortened, and its use effect will be seriously affected.Therefore, the correct maintenance of the mud scraper is particularly important.Below, we will introduce in detail the maintenance of the mud scraper.

Advantages of destratified solar submersible aerator

The solar submersible aerator is an oxygenated hydrolysis acidification tank and water circulation system equipment that uses solar power as a power device for water pollution prevention and control.It has the characteristics of low operating cost, excellent oxygenation effect, large flow rate, anti-clogging, long life and low operating noise.The more typical one is the destratified solar submersible aerator, which is very suitable for water quality with insufficient power supply systems such as river embankments, lakes, water conservancy projects, oxidation ponds, and man-made lakes.
