ADI Systems Inc.

ADI Systems Inc.

Overview:
ADI Systems Inc. is a subsidiary of the ADI Group, an
employee-owned multidisciplined engineering firm
established in 1945.

ADI Systems offers a wide range of environmental services to
customers from laboratory studies to full-scale treatment
systems. Waste treatment is the company's primary focus with
emphasis on high-BOD industrial wastewaters. In addition to
generic technology, ADI Systems offers proprietary technologies
in both anaerobic and aerobic biological wastewater treatment
applications. At the company's laboratory, research is done
on an ongoing basis with the aim of improving existing
technologies and developing new ones.

Company Growth:
The demand for wastewater treatment technologies has
grown worldwide. ADI, through local licensee companies,
now serves markets in the UK, Australia, Mexico, Turkey, Korea,
China, and India. The company also continues to serve Canada
and the USA in addition to other worldwide markets. ADI is
positioning itself to be open to new opportunities and to search
out suitable partners to further develop these new markets.

Company Mission:
ADI Systems provides a variety of services and processes as
part of an overall treatment train, thereby providing customers
with the best treatment system to suit their needs. Getting
the job done properly and with the best bottom line for the
customer, along with providing total customer satisfaction, is
our aim.

Market Background:
With the proliferation of regulations and restrictions
concerning effluent discharge, industries and municipalities
are under increased scrutiny to ensure that their wastewater
meets the required limits. This has led to an increased need
for reliable and efficient wastewater treatment systems that
consistently meet acceptable discharge levels.

Partnering:
Outside of Canada and the United States, ADI prefers to
work through local licensees. Currently, ADI has partners
in the UK, Mexico, India, Australia, Turkey, and Korea. ADI is
open to inquiries from overseas companies that are experienced
in the wastewater treatment field and interested in forming a
potential partnership.

Accomplishments:
ADI Group holds numerous patents and has won several
awards for service quality, innovation and management,
including the World Business Magazine Best Canadian
Service Company Award for two consecutive years.

Adi-hybrid Waste Treatment System

Anaerobic Adi-bvf System
The patented* ADI-BVF (Bulk Volume Fermenter) digester - a low- rate anaerobic treatment system that combines features of the upflow sludge blanket and anaerobic contact systems; will treat most warm waste streams of moderate to very high organic strength. Its major advantage is that equalization and primary treatment (i.e., DAF and primary clarification) are normally unnecessary because the system can accept wastewaters with very high organic strength and suspended solids concentrations. [*Canada Patent Nos. 1253266; 2,096,852; US Patent Nos. 4,672,691; 5,505,848; 5,587,080]

Adi-sbr Waste Treatment System
The ADI-SBR (sequencing batch reactor) system - an activated sludge type system in which different treatment operations are carried out in one vessel. Its combined efficiency makes the SBR a very flexible system and requires less land and less process equipment to maintain than other aeration systems. It can be used for BOD removal, nitrification, and denitrification.

Adi-amr (anaerobic Modular Reactor)
A modular reactor that installs quickly on site. The totally enclosed vessels ensure no odors will be emitted. Ideal for warm, high-strength, soluble waste streams. Appropriate for small flows.

Anaerobic Digester System.
In order to lessen the load on a town treatment plant, a BVF reactor was installed to treat the wastewater from the town's major wastewater contributor, a brewery. This brewery has an average wastewater flow of 300,000 gallons per day (1200 m3/d) with a COD of 3,000 milligrams per litre. The digester also treats septage and waste activated sludge. This results in a minimum amount of biosolids to be hauled to agricultural land twice per year. It is stable and does not cause odour complaints and adds tilth and fertilizer to the soil. The ADI system has performed exceptionally well, providing COD, BOD and SS removals of 90%. This high level of pretreatment has greatly lessened the burden on the city's treatment plant. The BVF digester's operating costs are minimal due to its simple design. Only a few hours per day are needed to operate the digester, no chemicals are added and the electrical energy required is very small. Situated on the edge of town, the plant is visually quite acceptable and a gas-tight floating membrane cover and gas collection system ensures no escape of objectionable odours. The biogas is burned in a boiler and the heat recovered is used to warm the digester.

Adi-hybrid Reactor.
The hybrid reactor is a combination of an upflow anaerobic sludge bed (UASB) and upflow fixed film (UFF) reactors. The lower 30-50 percent of the reactor volume is the UASB zone where a flocculant or granular sludge develops. Most of the organic stabilisation occurs in this sludge bed. The upper 50-70 percent of the reactor is the UFF section. In this zone, a cross-flow type media is used which provides an extensive surface area for the fixed-film biomass to develop and grow. This media is also effective at intercepting sludge bed solids and raw influent solids, and promoting their flocculation and return to the sludge bed below. The hybrid reactor is suitable for treating almost any wastewater where the load is primarily in the form of soluble COD. As a rule of thumb, the influent TSS loading should not exceed 10-20% of the COD load, and the fats, oil and grease concentrations should not exceed 100-200 mg/L. COD removals range from 80-95 percent. For removals higher than 95 percent, a two-stage system is required. The compact design of the ADI hybrid reactor allows it to fit into a small space. In 1995, an ADI hybrid system was installed in Korea to treat ethylene glycol wastewater at a polyester plant. The reactor volume is 500 m3 and the design loading is 10 kg COD/m3 d.
