● Data for the design and management of wastewater treatment facilities using the standard activated sludge method can be created, as all components including the sedimentation tank, raw water pump, aeration pump, sludge return mechanism, and automatic liquid temperature regulator are fully set up. ● The aeration tank and sedimentation tank are made of rigid transparent PVC, allowing for easy internal observation and providing excellent durability. ● The raw water pump uses a tube pump that does not cause blockages even with liquids containing slurry and fibrous materials. The injection volume can be freely adjusted, allowing for the selection of an appropriate retention time. ● An aeration pump is built-in for aeration purposes. The aeration pipe uses a pipe with small holes. It can be easily removed for cleaning. The air supply volume can be adjusted with a valve while being monitored by a flow meter. ● In the AS type, sludge returns to the aeration tank by its own weight, so the adjustment of sludge concentration is done by appropriately removing sludge. In the ASS-P type, settled sludge is returned to the aeration tank using a tube pump. The sludge return ratio is expressed as the volume of returned sludge relative to the raw water volume (%).

The "MJS-P Series" from Daitō Industrial is a portable water treatment testing device. You can adjust the speed by turning the knob while watching the digital tachometer. The stirring shaft can be freely raised or stopped in the middle. The exterior is made of anodized aluminum, so it does not rust. All models come with a reagent injection device, allowing you to inject reagents simultaneously by turning the side handle. 【Features】 ■ Speed adjustment possible while viewing the digital tachometer ■ Stirring shaft can be operated freely ■ Exterior made of anodized aluminum for rust prevention ■ Comes with two timers that can be automatically switched ■ Reagent injection possible simultaneously with operation *For more details, please refer to the catalog.

The "MJS Series" from Daido Industrial Co., Ltd. is a water treatment testing device made of stainless steel plates. There are two types: the H type, which has two timers that can automatically switch between rapid stirring and slow stirring, and the T type, which has three timers that can automatically switch between rapid stirring, slow stirring, and rest time. The T type can operate continuously with manual and automatic switching. All models come with a reagent injection device, allowing simultaneous injection of reagents by turning the handle on the side. 【Features】 ■ All exterior parts are made of stainless steel ■ Uses a digital tachometer ■ Two types of lighting available: back lighting and bottom/back lighting ■ Usable for a wide range of applications *For more details, please refer to the catalog.
