Biomedical Waste Treatment

The Hydroclave, operating under the principle of steam sterilization, is a double-walled cylindrical vessel which is fitted with a motor driven shaft, to which powerful fragmenting arms are attached that rotates inside the vessel.

Hydroclave provides 6log10 sterilization against bacillus stearothermophilus at 121 °C within 30 mins or 135°C within 15 mins.

Jacket steam heat will completely dehydrate the waste regardless of its original moisture content.

The dry sterile waste is further fine-shredded prior to a sanitary landfill disposal.

Thermal Destruction Facility

It operates a unit of Cleanclave Boiler imported from the Republic of Korea. This facility is used to destroy wastes such as non-halogenated plastics, dry wastes, bad order and off-specs dry products and related types of wastes.

It has state-of-the-art air filtration chamber which arrest particulates, NOx, SOx and even dioxins and furans thus producing clear and passing emissions.

It is composed of the thermal chamber in which wastes are fed. The heat produced is used to generate steam by the boiler found in the system. The steam is then directed to the Hydroclave of the Biomedical Waste Treatment facility for the treatment of hospital wastes. 

Thermal Oxidizer

With technology developed from South Korea, The Thermal Oxidizer System (TO) is the latest technology development of Cleanway Environmental Management Solutions, Inc. (CEMSI). The technology processes materials such as carton boxes, wood, paper, textile scraps, leather scraps, synthetic resins, organic sludge, oil contaminated materials, medical waste, and other combustible materials to deliver energy to its boiler. As part of its Waste to Energy Program, the TO is utilized by CEMSI’s existing treatment processes thereby reducing the use of conventional fuels such as LPG, fuel oils, or coal, thus cutting fuels costs and carbon footprint.

The systems are enclosed in a vacuum to mitigate odor and probable spread of pathogens. Oxidation is then introduced as the conveyors bring the homogenized wastes to the primary reaction chamber. Oxidation chambers operate at temperatures between 800°C to 1,150°C, with a combined reaction time of more than 3.5 seconds to come up with a fully oxidized ash product. The exothermic process produces heat for the shell and tube boiler to generate steam at 7bars, 165°C.

Physico-Chemical Treatment Facility

The unit detoxifies and neutralizes liquid inorganic wastes such as cyanide, hexavalent chromium, acid, alkali and chemical wastes containing heavy metals like zinc, nickel, copper and lead.

It is a combination of physical treatment such as mixing, sedimentation and filtration as well as chemical treatment such as oxidation, reduction, neutralization, and precipitation.

Effluent water is passed through a mixed bed filter and pH adjusted prior to discharge. Effluent will pass DENR- DAO 35 standards,

Wastewater Treatment Facility

A centralized wastewater treatment plant processes water from different treatment lines including:

  • Effluent of Physico-chemical treatment
  • Medical wastes treatment facility
  • Gray water from Anaerobic Digester
  • Domestic wastewater
  • Leachate from landfill

It is a combination of chemical and biological treatment. Treated water undergo final polishing process to achieve standard parameters prior to discharge.

Anaerobic Digester Facility

The facility operates two chambers that arrest oxygen to support anaerobic respiration of microorganisms that destroy organic components of wastewater i.e. milk, fats, proteins and sugar. Produced biogas, composed of methane and carbon dioxide is used to power a generator set which in turn supplies electricity needed by nearby facilities. A flaring system is added for emergency purposes.

Wastes are loaded in the collection tank, that flows to the distribution tank via gravity which channels them to the two digesters. At the end of 21 days, treated wastewater comes out as gray water which is directed to the Wastewater Treatment Plant (WTP) prior to discharge. The facility also has a drying bed to remove solid particles.

Decontamination, Deconstruction and Recovery Facility

It operates a unit of 50-HP shredder, 40-HP shredder and a baler system. Wastes, such as expired pharmaceutical and consumer goods products, plastic bottles and containers, tin cans and drums are processed.

Expired and off-specs goods are destroyed directly using the equipment found in this facility. Contaminated wastes will undergo decontamination using appropriate treatment procedure prior to destruction. After quality inspection, destroyed materials are either recovered and sent to a recycling facility or landfilled.

Bioremediation / Landfarming Facility

The facility manages to degrade organic wastes and incorporate the degradation product into the soil. It is composed of bioremediation bed with high density polyethylene (HDPE) lining to prevent seepage of contaminants into the ground. A backhoe is employed to mix soil and wastes within the facility. During rainy season, the area is covered completely to prevent soaking with rainwater.

Wastes are loaded to the bioremediation bed with predetermined amount of soil. During initial mixing, inoculum is added to incorporate microorganisms into the system. The soil and waste mixture is turned every three (3) days to ensure proper degradation. Moisture and temperature are regularly monitored.

Solvent/Oil Recovery Facility

The solvent/oil recovery unit processes washing solvents, contaminated isopropyl alcohol and acetone, toluene and other spent oil / solvents.

It consists of a boiling chamber, heat source, condenser and solvent tanks. By batch distillation, the contaminated solvents can be processed and recovered.

Bulb Crushing Facility

The Bulb Eater is the machine that processes, or crushes, spent fluorescent lamps into small fragments.

Bulbs are crushed by piece. The white powder as well as the mercury vapour is filtered by bulb eater filtration systems. The High Efficiency Particulate Air (HEPA) filter that captures over 99.97% of the particulate matter and carbon filter that captures the mercury vapor. The filters and crushed bulbs are encapsulated and disposed in the Secure Landfill.

Solidification and Stabilization Facility

The process is applied to wastewater sludge or solid wastes containing heavy metals such as lead, arsenic, chromium, cadmium, boron, selenium and mercury.

This treatment prevents the earth from being contaminated with toxic substances that may leach out from solid hazardous wastes. Toxicity Characteristic Leaching Procedure (TCLP) test is be conducted on each batch prior to disposal in a Secure Landfill.

Composting Facility

The facility is used to convert solid organic wastes into soil amendment. It is composed of four composting tubs equipped with a gantry system for proper mixing.

Wastes are loaded to the tubs with predetermined amount of activator and bulking agents such as green materials. During initial mixing, inoculum is added to incorporate microorganisms into the system. Moisture and temperature of the compost are regularly monitored.
