Product Feature

Loss-in-Weight Feeder controls weight released from the feeder by weighing it instantaneously. It is a suitable type for measurement of powdery material that allows easy blockage of scattering and odor of measured material during input/output, which is difficult for belt type Constant Feeder Weigher to deal with. We are also manufacturing explosion proof type that can be used for area that has risk of dust explosion. Kyung Sung D.S supplies scale with high accuracy by using the latest model of load cell and controller with technology accumulated for many years. It can be used as either continuous or batch type, show its ability to improve productivity and accuracy of product, and minimize material loss on small quantity batch production process. However, to improve measurement, the time interval for recharge should be shortened. For feeder, it uses various valves, screw feeder, and rotary feeder, and for ejector, it uses screw feeder, table feeder, vibrating feeder, and rotary feeder.

Shows strong points of centrifugal and axial fan.

KOREA SLOT well screen is a filtering device that serves as the intake portion of wells constructed in unconsolidated or

semi-consolidated aquifers. The screen permits water to enter the well from the saturated aquifer, and prevents

sediment from entering the well, and serves structurally to support the aquifer material.

 

Continuous-slot well screens provide more intake area per unit area of screen surface than any other types of screen.

This type of screen has maximum open area. For best well efficiency, the percentage of open area in a screen should be

the same as, or great than, the average porosity of the aquifer material. Water flows more freely through a screen with

a large intake area compare to one with limited open area. The entrance velocity is low, therefore head loss for the

screen is at a minimum and finally minimizes drawdown in the well.

 

Reference 1) Radial Collector Well

 

Radial collector wells are wells whose screens have a radial or horizontal component. Types of radial wells include

collector wells, horizontally directionally drilled wells, and slant or horizontal wells. Collector wells are the most common

type of radial wells. The basic components of collector well design are a veitical shaft with horizontal screen laterals.

These laterals typically extend up to tens of hundreds of meters and vary in number based on aquifer characteristics.

Radial collector wells take advantage of natural filtration through aquifer materials, which reduces treatment costs.

Maintenance is reduced as the longer horizontal screens reduce water velocity, thereby reducing well head losses and

clogging. Furthermore, lateral well screens are able to exploit the maximum saturated thickness of shallow aquifers. For

example, up to 500 m of horizontal well screen can be developed in formations that would accommodate only 20 m of

vertical well screen. Horizontal directionally drilled (HDD) wells, which are widely used in the oil and gas industry, are

now being developed for groundwater applications.

 

Reference 2, Riverbed Filtration System.

The riverbed filtration process extracts water from the vertical well from the river shoreline. The vertical well connects

with horizontal (lateral) screen pipes that are the intake screens for filtrated river water through the riverbed aquifer

layer. This process secures an indirect water intake source and helps to improve river water quality as well as to insure

river water is maintenance.

The seawater intake system indirectly intakes seawater that is naturally filtrated through the sand layer of the sea.

Benefits of Riverbed Filtration are:

1. Utilizes the natural filtration of the riverbed aquifer

2. Removes nutrient salts & pollution substances

3. Reduced facility investment costs

4. Reduced maintenance costs

5. Use of chemicals not required

6. No sludge generated
