Introduction Established in 2007, Holly Technology is a domestic forerunner in producing environmental equipments and parts used for sewage treatment. ln line with the principle of Customer first”, our company has developed into a comprehensive enterprise integrating production, trading, design and installation service of sewage treatment equipments. After years of exploring and practices, we have built up complete and scientific quality system as well as perfect after-sale service system.


Nano Bubble Generator
Nano Bubble Generator is presented by HOLLY,a promising CE and ISO certificated product utilized with its own nano bubble technology,its application range is particularly wide in different industries and has huge development potential as the functional properties of nano bubble: bubbles with anion,bubbles explosion with antiseptic effect,dissolved oxygen in water increasing rapidly,high efficiency and energy saving in water treatment. Advanced & mature technology and development continuing to expand its application range,market will grow.The nano bubble generator could work separately or work together with its corresponding models of Oxygen Generator or Ozone Generator which could replace the current high-pressure decompression dissolved flotation of fine bubbles and part of the aeration equipment.
Mechanical Bar Screen
HLCF Mechanical Bar Screen is provided with several special-shaped teeth which are assembled on the teeth axis based on certain ordering, forming the sealed teeth chain. The lower part is installed in the water inlet. If the chain wheel rotates directionally with even speed, the whole rake chain will move accordingly. Under such circumstance, the solid sundries attached on the tooth will be separated from liquid and the fluid will low away through the gap. When rake chain arrives at its upper end, each group of rakes will carry on self cleaning by dropping out most of the solid material under gravity and guideline rail, while the rest of the solid will be tidied clean by back running brush.The whole process is carried out continuously and automatically so as to achieve the goal of solid-liquid separation.
Polymer Dosing System
The Polymer dosing system is range of simple and flexible as well as economic and efficient preparation systems for polymers. The product range cover from 1 to 3 chamber systems and associated dosing stations for both dry and liquid polymers. The systems are equipped with precise water and level material to secure efficient and economic operation of the systems. We customize the systems to match the application and customer needs, i.e. volume of polymers in kilogram per hour or concentration of polymers in the prepared solution or ripening time.
Fine Bubble Tube Diffuser
Fine Bubble Tube Diffuser can be connected on one side or in pairs to different rectangular and round tubes (ABS material) with the appropriate adapter. The membranes are manufactured with premium quality EPDM material and are available with fine or coarse-bubble perforation.The support tubes (ABS or PVC material) can be reused when membrane are replaced. The units office maximum performance at minimum cost and require minimum maintenance.
Submersible Mixer
The submersible mixers are mainly used for the purposes of mixing, agitating and making ring flows in the process of municipal and industrial sewage treatment and can also be used as the maintenance equipment for the landscape water environment,through agitation, they can achieve the function of creating water flow,improving the quality of the water body,increasing the oxygen content in water and effectively preventing the sedimentation of the suspended Substances
MBBR Bio Filter Media
Bio filter media, used in Integrated Fixed-lm Activated Sludge (IFAS) and moving bed biofilm reaction (MBBR) system.The wastewater goes through suspending media of MBBR reactor, forming biological membrane on the surface of media gradually. With the action of microbial on the biological membrane, wastewater is purified. MBBR media can move freely in the reactor with the mixing of the water. For the aerobic reactor, the aeration will make the media move; for the anaerobic reactor, mechanic mixing will make the media move. Our MBBR media is new-developed media, has better treatment effect compared with traditional media.
Dissolved Air Flotation(DAF) System
Dissolved Air Flotation (DAF) is an efficient flotation method for water clarification.The term refers to the method of producing flotation by dissolving air in the water under pressure and then releasing the pressure.When the pressure is released the solution becomes supersaturated with air as millions of small bubbles form.These bubbles attach to any particles in the water causing their density to become less than that of water.The particles then rapidly float to the surface for collection and removal, leaving the clarified water behind.
Fish Farming Aquaculture Drum Filter
The drum filter is mainly composed of four parts: tank component, roller component, backwash component and liquid level automatic control component. It is made of non-toxic seawater corrosion-resistant high-quality engineering plastic materials. A stainless steel filter screen is fixed on the rotatable drum, and the tiny suspended substances in the water are separated and filtered through the screen and finally achieve solid-liquid separation. During the filtering process, small suspended particles in the water will cause the screen to be blocked. When the screen is blocked, the liquid level automatic control component works, and the backwash water pump and roller reducer automatically start working to make the screen timely cleaning to keep the equipment in good working condition.
Dewatering Screw Press
HLDS Multi-disc Sludge Dewatering Screw Press belongs to the screw press, it’s clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction.
Fine Bubble Diffuser
Fine bubble disc diffuser features a unique split pattern and slit shapes, which can disperse air bubbles in an extremely fine and uniform pattern for high oxygen transfer efficiency. A much highly effective and integrated check valve enables the aeration zones to be easily shut down for air-on/air-off applications. It can be operated over a wide range of airflows with minimum maintenance for long term performance.
