[INQ. NO. 1707M11] Hyorim Industry displayed the non-metallic sludge collector that continuously collects sludge (solid substances sank when precipitating sewage) in a settling tank of sewage/waste water treatment plants.
The non-metallic sludge collector is a device (basket) that removes inert matters in the raw water by installing in an influent channel of water intake/purification plants.
Besides, they also displayed the movable band screen (TWS) and the upflow inclination plate sinking set. The movable bank screen is the same as the non-metallic sludge collector in that it continuously supplies wastewater by installing in an influent channel of water intake/purification plants. The upflow inclination plate sinking set evenly controls the rising flow in a settling tank.
Director Byun Jong-yun of the technology and sales team of the environmental business division of Hyorim Industry said, “As they are made of non-metallic materials, the non-metallic sludge collector and the movable band screen are light. They also have the merit of filtering small sludge, not filtered in a waterway, over again.”

[INQ. NO. 1707M10] Hansu Technical Service (HTS), the comprehensive water treatment company providing design, manufacturing, construction and test-drive of water treatment facilities, displayed the new-style high-rate coagulative precipitation unit.
For a precipitation tank, HTS makes it possible to treat 2.5M in diameter, instead of 16M. It also contributes to simplification of cohesion and precipitation treatment by treating in ‘one’ tank by applying a line mix device.
Among the company’s products are; fluidized bed carrier biological treatment device (BM-SK); new-style high-rate pressurizing and float tank (KURITA FLOTATION); KHDS (Kurita High Density Solids); new-style high-rate cohesion and precipitation device (SEDIMAX-SO); carrier-type anaerobic biological treatment device (BS-TK); sludge reduction biological treatment device (BP-SR); and containing waste water treatment facility (BP-FO).

Deputy department head Kim Jeong-gu from the new business team of the plant business division of Hansu Technical Service emphasized, “It is the method of eliminating impurities by increasing the circulating rate of water using micro bubbles. It prevents the leaking of aggregates by duplexing the inner structure.”

[INQ. NO. 1707M09] Cheonbo Engineering introduced the pneumatic conveyor that transfers diverse inert matters freely, vertically or horizontally, using compressed air.
The pneumatic conveyor is simple to install and does not require a large area for installation, so it can be used in restricted spaces. Also, the lifespan of the device is longer than other types and unmanned operation is available with the automatic method. Its transportation capability is maximum 80m horizontally and 25m vertically.
Meanwhile, Cheonbo Engineering has separately established the Ewha Ecosystem and produced the sewerage/waste water treatment facility, notably the Drum Screen.
Senior Executive Choi Suk-gyo of Ewha Ecosystem Co., Ltd. explained, “The pneumatic conveyor is a product displayed for the first time in Korea. It uses a method whereby after receiving inert matters, a valve is automatically locked and compressed air pushes inert matters.”

[INQ. NO. 1707M08] There are various models of underwater cleaning robots, K1, K3, K7, etc., that can clean underwater sites while monitoring. ZETA CREZEN displayed robots that reduce production costs by decreasing personnel expenses and preventing industrial accidents since robots would execute the underwater cleaning. K3 is small and light so it is suitable for farms with little deposits.
K3 can be remotely controlled through a powerful pump and a rotating brush. It is suitably designed for cleaning the inside of reservoirs or deposits using video technology installed on the machine.
In particular, K7 can save moving images by using an infrared camera and go up an incline by using inhaling equipment. It is also easy to maintain and repair thanks to the integrated module.
Director Gwon Hee-woong from the equipment business team of ZETA CREZEN said, “it is generally small but it has the advantage that it can be controlled remotely with robots in various sizes.” He added, “It has achieved great popularity overseas such as at the Kazakhstan Xabar 24 National Broadcast.”

[INQ. NO. 1707M07] Jeong Woo Environmental Technology Inc. introduced the recycling water treatment facility, which treats locally generated wastewater individually or collectively so that wastewater can be reused without being discharged into public sewers.
In fact, since ‘the act on promoting and supporting water reclamation’ was enacted on July 2016, buildings using water more than a certain amount are obliged to build and operate a recycling water treatment facility.
The ISAC MBR water treatment system diagnoses and washes a membrane with the world’s first built-in IoT technology. Executive Director Lim Dong-gwan from Jeong Woo ENT explained, “the external circulating type MBR process is a technology that is already constructed and verified in sewage treatment plants. It has excellent performance, economic feasibility and maintenance.”

[INQ. NO. 1707M06] IOREX has developed IOREX – the ionizing water treatment equipment with its own technology, which is extremely efficient to renew worn out water pipes. It currently proves its outstanding efficiency at the water supply facilities of numerous municipalities, POSCO, Hyundai Heavy Industry Corp., KORAIL, GS Caltex, Seoul National University of Education, lots of houses, apartments, ranches, farms, and so forth.
Old water pipelines may have rust, scale, and slime problems. IOREX, is a water treatment system by water ionization that can prevent or remove rust and scale in pipelines simply by installing it in any water pipe, for clean and efficient maintenance. Iorex is an economical and environmentally friendly water treatment system using the flow of water as its source of power, a physical and positive method. Also, IOREX is currently certified by NSF International. This system allows easy installation, short-term water outage and traffic control. For maximized safety, it uses carbon, a highly body-friendly material. As it is an eco-friendly product, it gives out no chemicals. It is economical – only one time installation is needed for semi-permanent use. It is also very practical as there is no drop in water pressure and it is appropriate to control water quality both in Korea and globally.

[INQ. NO. 1707M05] Wekotec displayed the water quality TMS devices such as CODs, automatic analyzers, residual chlorine measuring devices, etc.
By downsizing the products, the company can more customer convenience. They also reproduced a precise measurement value using a patented ‘syringe pump module’ technology.
Furthermore, Wekotec has cut a figure in the measuring instrument field by obtaining a total of three form certificates (WEKO-COD, WEKO-TN and WEKO-TP) for the relevant water quality TMS product.
Team Leader Cho Hyung-jin from the management support department of Wekotec said, “It improved both convenience and precision by applying a small number of reagents simultaneously without pumping each reagent one by one.”

[INQ. NO. 1707M03] KiSAN Machinery has been growing as a company that manufactures professional submersible devices with a global-level competitive edge based on perpetual challenges and unstinted investment in development of new technology since its establishment in 1996.
Submersible aerators from KiSAN Machinery are composed of a submerged motor mounted with a reducer, an impeller, a casing and an air-blow rotor. It miniaturizes bubbles with the high-tech action of a water current by combining ideal circulation inside a tank by using a water current and the air-blow system.
Water is sucked down and discharged from top to bottom. It becomes a current spread as an almost horizontal radial shape from an air blow hole. The purpose of aeration is oxygen movement and mixed stirring. However, stirring performance is also excellent since a water current spread as a radial shape in the bottom of a tank can severely fluidize the bottom of a tank where precipitation occurs easily.
This product is for both stirring and aeration and used to treat denitrification and phosphate. It can deliver oxygen very effectively thanks to its high-efficiency design. It is easy to control the oxygen supply by increasing or on-off controlling the amount of air supply. It is used for aeration of septic tanks in sewage & waste water treatment plants and industrial factories.
