Waterworks process flow(1):

Improved hydraulic circulation clarifying tank + DA863 filtration technology

 

Process flow

 

Features

This process consists of high-efficiency mixer, improved hydraulic circulation clarifying tank and D-type filter, characters of each process show as follow:

 

1. High-efficiency mixer has characters of less head loss, simple equipment, without civil structures, no external power equipment and good mixing effect within the design flow range.

 

2. Improved hydraulic circulation clarifying tank has characters of no mechanical agitation and simple structure. Its general water turbidity is less than 500NTU and during short time it allows 2000NTU. However, its dosage is a bit large and it consumes head loss.

 

3. DA863 filtration technology has characters of high filtration rate, high precision, low backwash water consumption, resistance against shock loading, the use of air-water backwash and surface-water sweep, good washing effect. Under same water quantity, it can effectively reduce the working area, save construction investment, and improve water quality;

 

Therefore, this process has characteristics of small footprint,low investment, high water turbidity and good treatment effect. Combination D-type filter with improved hydraulic circulation clarifying tank can effectively reduce the covering area of the waterworks, save the costs of first civil engineering and machinery investment. 

 

Core Techniques

Improved hydraulic circulation clarifying tank, DA863 filtration technology and High-efficiency mixer.

 

 

Scope of application

This process is mainly used for handling suspended solids and colloidal material in water, generally applied in conventional treatment of drinking water which is from surface water(such as rivers, etc.).

Waterworks process flow(2):

High-efficiency sedimentation tank+ DA863 filtration technology

 

Process flow

 

 

Features

This process consists of high-efficiency mixer, high-efficiency sedimentation tank and DA863 filtration technology,characters of each process show as follow:

 

1. High-efficiency mixer has characters of less head loss, simple equipment, without civil structures, no external power equipment and good mixing effect within the design flow range.

2. High-efficiency sedimentation tank
  (1) Inclined-tube sedimentation tank: with the advantages of high precipitation efficiency, small cell body and small land occupation. The water turbidity is generally 500-0-1000 NTU, the handling ability of single tank should not be too large;
  (2) Advection sedimentation tanks: with the advantages of lower cost, easier operation, simpler construction, stronger adaptability of the raw water turbidity, greater potential and more stable handling ability. The general water turbidity is less than 5000NTU, but the land occupation is larger.

 

3. DA863 filtration technology has characters of high filtration rate, high precision, low backwash water consumption, resistance against shock loading, the use of air-water backwash and surface-water sweep, good washing effect. Under same water quantity, it can effectively reduce the working area, save construction investment, and improve water quality;

 

Therefore, this process has characteristics of small footprint, low investment, high water turbidity and good treatment effect.

Core Techniques

High-efficiency sedimentation tank, DA863 filtration technology and high-efficiency mixer.

 

 

Scope of application

This process is suitable for the water which has less sand content and suspended solids of high concentration up to 5000NTU. Its effluent is less than 10NTU. The process is particularly applicable to the waterworks of large water quantity, high turbidity and low covering area.
