FINE BUBBLE DISC AERATION

SPECIFICATION: HMD200/270/340

QUALIFIED MEMBRANE MATERIAL

Rubber Membrane

Use hig-quality rubber raw material. and customize material composition and

proportion according to the requirement of aeration condition, Excellent physical and

chemical properties effectively prevent the contraction, hardening and aging of the

diaphragm and extend the product service life.

Plastic Sructure

Polypropylene fiber and glass fiber are selected, with additives such as anti-aging. This

material combination enables the product to retain sufficient strength while having

excellent toughness. In addition, product is durable and performance stable with the

ability of anti-oxidation, anti-impact, anti-creep, and anti-comossion.

RELIABLE PROCESSING TECHNOLOGY

• Professional surface treatment process. Smooth surface prevents the membrane from scaling.

• Tiny bubble reduces destruction effect to activated sludge particle and maintains the system biological activity.

• Membarne producing adopts passing mould technology. With uniform material processing, membrane’s anti-tearing stength and multi direction anti-tearing strength are stromg.

• Mechanical assembly production. Reliable product quality and sufficient product stock.

SPECIAL DESIGN FOR PRODUCT STRUCTURE

01. Six “L” clamping strips are designed on the outside of the aerator cover, which can prevent the aerator from falling off the membrane caused by the creep of the plastic cover due to the long time of bearing the expansion of the diaphragm and the external

tension pressure.

02. Special check structure design. There is a convex check ring around air vent of the supporting plate, and round bulge on the central inner side of the rubber membrane. When aeration stops, the membrane firmly covers the check ring under the action of its own-rebound and water depth pressure. At the same time, the convex on the membrane is sluck inside of the plate check ring, effectively preventing the backflow of mud water. In addition, the protrussion on the inner side of the diaphragm can guide the air flow to diffuse to surrounding, reduce the damage to the membrane in the long-term high-speed air flow, effectively avoid rupture of the membrane central area caused by overstreched, and extend membrane service life.

03. HMD disc diffuser is equipped with anti-deformation strengthening structure, thicken reinforcement structure and anti-falling seal bans to ensure the stability of the product under high strength and long-term operating conditions and prevent the membrane from falling off.

04. Special air flow channel design. Optimize the flow pattern of air flow. Reduce the loss of resistance along the path.

05. Strengthen the screw of the root of aeration to prevent the thread fracture.

PHYSICAL AND DIAMETER PROPERTIES

MODEL AND MEMBRANE SELECTION

HMD-340

High efficiency and energy saving, wide aeration area, even bubble distribution. At the same air flow, it has higher oxygen transfer

efficiency and lower resistance loss compared withe other size diffuser. It is recommended to use with a dedicated fixed adapter.

HMD-270

Moderate performance. Diameter 270mm difusser enjoys the dominance among the customer.

HMD-200

As diameter 200mm difusser volume is small, so it bears small pressure from different aspects. Because of that, the aeration system

will be more stable and reliable. It is suitable for all high strength working condition.

EPDM

It is suitable for municipal sewage and most industrial sewage. Good physical performance. Resist tearing. Keep shape with years usage. It is not suitable for organic solvents, greases, and high concentration metal salts.

The material is suitable, the membrane is not easy to harden and shrink, and has good resistance to organic solvents and grease

sewage . However, its physical properties are not as good as EPDM, it is suitable for the fields of high oil content and high temperature

industrial wastewater.

PTFE Layer

It has good tolerance to solvents and greases etc. Strong chemical corrosion resistance, less surface scaling, less maintenance, and long service life. It is suitable for hard-solved industrial sewage, such as pulp, retinery, landfill etc.

CONNECTOR

During aeration operation, the aeration system is in a state of continuous high strength vibration. Also, heat expansion and cold shrinkcage are common during operation. So it has high quality demand to aeration link parts.

Rubber Saddle Universal Type

HC- rubber saddle with 3/4NPT internal thread can be used for installation of HMD200/270/340 disc aerator on various plastic pipes such as ABS, UPVC, etc. It is suitable for pipe outside diameter range of 75-110mm and wall thickness of 4-8mm. It can be used seperately in general stenght condition. Pipe opening diameter is 35mm.

SPECIAL BUBBLE CUTTING MODE

EFFICIENT CUTTING

The air flow is ejected from the nozzle at high speed, forming a strong negative pressure at the bottom of the aerator, and the high sewage and activated sludge at the bottom of the aerator are sucked into the aerator to achieve the first efficient cutting.

SECOND TIME EFFICIENT CUTTING

The mixture flows through the spiral guide plate, and under the action of the rotary cutter, generating the violent vortex flow. This is the second efficient cutting.

THIRD TIME EFFICIENT CUTTING

Then, the spiral airflow is cut through the specially designed multi-layer cutting piece, after eight times multiple cutting, a large number of mm air bubbles and some micro-nano air bubbles are produced, achieving the third efficient cutting.

FOURTH TIME EFFICIENT CUTTING

The spiral flow jets from the swirl aerator with high speed, diffusing around under the action of centrifugal force, forming many small whirlpools in the flow field, achieving the fourth efficient cutting.

DIFFUSER CYLINDER

Overview

TS diffusing cylinder is stainless steel fine bubble aerator with a stationary diffusing cylinder developed especially for aeration of active sludge tank and it has no moveable parts.Air blown to bottom passes through the aerator together with water. Then, the air and water are mixed with each other and changed into ultra fine bubbles by stirring them.the bubbles exchange, oxidize, absorb and deaerate the upper and lower fluid materials continuously and effectively.
