FAQs-Wastewater Treatment Plant

A Sewage Treatment Plant (STP) treats sewage and wastewater before it is discharged or reused. The treatment process removes contaminants from wastewater and helps reduce pollution, protect water resources, and support safer wastewater management.

An STP treats wastewater through several stages. Depending on the technology, these can include separation and sedimentation, biological treatment, final sedimentation, and disinfection. The aim is to reduce pollutants and produce treated water suitable for its intended discharge or reuse.

Johkasou is a decentralized wastewater treatment system developed in Japan. It treats wastewater close to where it is generated, making it particularly useful for buildings and sites where a centralized sewer connection is unavailable or impractical.

Daiki Axis provides prefabricated FRP Johkasou systems for wastewater treatment.

A traditional RCC STP is generally constructed on-site and can require considerable civil work and installation space. Johkasou uses prefabricated FRP treatment modules, which can reduce on-site construction requirements and provide a compact option for decentralized wastewater treatment.

Yes. Daiki Axis Bangladesh provides Johkasou-based sewage and wastewater treatment solutions in Bangladesh. Its services include project assessment, STP design and engineering, supply and installation, testing and commissioning, and operation and maintenance support.

Johkasou systems can be considered for apartments, hotels, offices, hospitals, factories, schools, and other properties that require on-site wastewater treatment. The appropriate system and capacity depend on wastewater volume, site conditions, available space, and treatment requirements.

Yes. A compact Johkasou STP can be suitable for apartment and residential projects, particularly where installation space is limited. The correct system should be selected based on expected wastewater flow, occupancy, available space, and project requirements.

Yes. STP systems can be designed for commercial buildings such as offices, hotels, restaurants, and other developments. Capacity and system design should be determined from expected wastewater generation, occupancy, available installation space, and required treated-water quality.

Daiki Axis Bangladesh provides wastewater treatment solutions for different project applications, including factories. Industrial projects require proper assessment because wastewater characteristics can vary significantly depending on the manufacturing process and activities at the site.

An FRP-based STP uses Fiber Reinforced Plastic for its prefabricated treatment structure. FRP systems can provide a lightweight, corrosion-resistant and compact alternative to conventional site-built structures. Daiki Axis Johkasou products use FRP as the main material.

STP capacity should be selected according to the amount of wastewater the property is expected to generate. Occupancy, number of units, building use, daily wastewater flow, peak loads, available space, and discharge or reuse requirements should all be considered before selecting a capacity.

A site and wastewater assessment is therefore more reliable than choosing an STP based only on building size.

There is no single fixed price for every STP. Cost varies with treatment capacity, technology, wastewater characteristics, site conditions, installation requirements, equipment, civil work, and operation and maintenance needs.

A capacity-based technical assessment is the better way to obtain an accurate project quotation.

Yes. Every properly operating wastewater treatment system requires inspection and maintenance. Depending on the system, this can include checking equipment, monitoring treatment performance, cleaning, servicing pumps and blowers, and periodic sludge management.

Daiki Axis Bangladesh provides operation and maintenance support for STP projects.

Treated wastewater may be reused for appropriate non-potable applications when the required treatment quality and applicable standards are met. Daiki Axis materials identify applications such as gardening and other non-drinking uses for treated water.

Decentralized wastewater treatment means treating wastewater at or close to the place where it is generated rather than relying entirely on a centralized sewer and treatment network. It can be useful for individual buildings, developments, institutions, and communities requiring local wastewater management.

A packaged wastewater treatment plant is a prefabricated treatment system in which major treatment components are manufactured before being delivered to the project site. This can reduce the amount of construction required on-site and make installation more practical where space or construction time is limited.

Installation time depends on plant capacity, technology, site access, civil preparation, utilities, and project conditions. Prefabricated systems can reduce on-site construction compared with fully site-built treatment plants, but an installation timeline should be confirmed after assessing the specific project.

Yes. Daiki Axis Bangladesh provides STP-related services including assessment and capacity planning, design and engineering, supply and installation, testing and commissioning, and operation and maintenance support.

Start by checking whether the supplier can assess wastewater flow, recommend the correct treatment capacity, provide clear technical specifications, handle installation and commissioning, and offer reliable after-sales maintenance.

Also review completed projects and ask for technical documentation rather than choosing a system based only on the lowest initial price.

Daiki Axis Bangladesh's website currently lists completed and ongoing Johkasou STP projects across residential, industrial, healthcare, hospitality and public-sector applications.

Contact Daiki Axis Bangladesh with basic project information such as the project type, location, expected occupancy or wastewater volume, available installation space, and any known treatment or reuse requirements. The technical team can then assess the requirements and recommend an appropriate STP solution.
