www.biocentury.com.mx
Bio Century S.A. de C.V. • Bio Century S.A. de C.V., a Mexican company, established in 1994, specializes in development of Water Technology, and the application derived from it research since 1988. • This New Technology has an impact not only for the Water Treatment Industry, also in other several sectors that have been understudied with economic benefits.
Clean Master® Technology • Consists on a Biochemical Ionization. Only with CMT products, the Water's Magnetic Fields are excited in a controlled, self catalyzed reaction. • This process modifies the water molecules physic and chemical interactions with themselves, present solutes and suspended particles.
Clean Master® Technology
• CMT has important advantages in Water Treatment when
compared with present alternatives, such as:
– CMT facilities requires less installation area
– Easily expandable
– Lower cost conversion projects
– Lower cost in the installation and operation of Water Reuse
Treatment facilities
– Sludge production is about 3 times lower than biological plant
– Odor reduces up to 99.99%
• Water discharge treatment can be achieved in a single
step, and two steps for reuse purposes.
Clean Master® Technology • CMT produces Functional Water, its main characteristic is the modification of its physic and chemical behavior with unique results; some examples are presented in Cooling Tower Chemical Treatment and removal of phenols/heavy metals in water.

Performance increase • Water modification stabilizes oil in smaller particles, resulting in a more homogenous emulsion. • As a result less viscosity and oil performance is presented, allowing longer service periods.
Emulsion breaking for reuse • As an opposite effect, by increasing water modification the emulsion is broken due charges increase. • Since there is no oil chemical change, it can by reconditioned for reuse in process, disposed for confinement or used as an alternative energy source.
Refinery waste water treatment “ING. ANTONIO M. AMOR” (RIAMA), Located in Salamanca, Guanajuato, México.
Refinery waste water treatment • A treatment test was made with the RIAMA’s industrial waste water for discharge and possible reuse in cooling tower makeup, results were excellent and couldn’t be match by any other technology.
10.2 Conclusion 10.2.1 The main conclusion is that CMT meets the requirements to use treated refinery waste water in the cooling tower systems certified by the Mexican Institute of Water Technology. 10.2.2 Proyectos y Evaluaciones de México, S.A. (third party certifier) certifies that the results of the Refinery waste water treatment with the CMT comply with PEMEX specifications and Federal Discharge Water Quality Regulation.
PHENOLS REMOTION TEST IN STRIPPED SOUR WATER
“ING. HÉCTOR R. LARA SOSA” REFINERY
Located in Cadereyta, Nuevo León, México.REFINERY RESULTS • The treatment of stripped sour water was done in a 15.85 GPM pilot plant consisting in: homogenizer tank, sedimentation plate tank, pumping station and final sand/activated carbon filtration stage. Total residence time: 2 hours.
REFINERY RESULTS • Stripped sour water contained more than 60 mg/L of phenols. The objective was it’s reduction to meet biological waste water treatment plant specification of 1.6 mg/L.
REFNIERY RESULTS
CONCLUSIONS • CMT treatment using conventional equipment removed 99.9 % phenols in only 2 hours, this isn’t economically possible using other technologies, either at bench, pilot or industrial scale.

OIL DEHYDRATION AND DESALTING
“ING. ANTONIO M. AMOR”
REFINERY
Located in Salamanca, Guanajuato, México.Actual treatment • Salt in oil reduce its value by increasing processing costs from levels as low as 1 lb/ 1,000 BLS, higher concentrations cause systems to deteriorate faster, which makes desalting an important stage in the refinement process. • RIAMA’s desalting units use a mixture 70/30 of stripped sour water/well water in 5 % proportion in oil. Stripped sour water by itself doesn’t meet required quality for this application.
Procedure • A bench test was performed at RIAMA’s staff and facilities using 100 % stripped sour water treated with CMT products.

NaCl Lb/1,000 BlsResults • This results were obtained without using any product normally added to oil or water. • A higher than 94 % salt remotion was achieved (measure method doesn’t detect lower levels than reported) without emulsion formation reducing water and sediment in oil more than 75 %.
Conclusions • CMT produces a modification to stripped sour water that increases oil desalting process efficiency that at industrial level will reduce well water consumption and chemicals costs. • This treatment can be applied in off shore operations, increasing oil quality and minimizing transports costs and equipment maintenance.
Cooling Towers www.biocentury.com.mx
Advantages of CMT application
– On line scale remotion and salt inactivation.
– Corrosion and bacterial control.
– Equal or lower operative cost as those using
conventional technology.
– Less equipment maintenances (heat exchangers)
increasing operative interval up to 5 times, including
the possibility of on line cleaning service.
– Make up water reduction up to 50 % bleeding flow.
– Pollutant concentration increase such as fats and oils
can be controlled with out additional chemicals.
– Chemicals aren’t aggressive to pipes or equipments.
– Operation is simplified due a less number of
chemicals used.Example • Industrial water cooling tower of 30,000 GPM in APM located in Monterrey, México (rolled steel manufacturer for automobile industry), water used to reduce steel temperature before and during rolling, the pollution in the system was originated from iron, grease and oils (leaks).
Example
• Conditions before and during CMT
treatment.

* Cycles calculation using make up water consumption.Economic benefit • The CMT application generated savings of 28,530,600 water gallons per month, plus savings in maintenance, energy, chemicals and labor hours in previous treatment operative problems. • Additionally benefits over product quality were due to defect elimination on surface, increasing hardness by using functional water, as well as correcting uniform water spreading system.

Chloride inactivation • Chloride concentration in water is highly monitored for its corrosive effect on steel. Since CMT modifies water, salts in it present a different behavior than expected according to traditional knowledge. • Several test were made using SEM (Electronic microscopy) by APM staff to observe the effect of different concentrations of the chloride in the process.
Chloride inactivation • Chloride levels as higher as 600 mg/L didn’t generated defects to the steel, this is 5 times chloride in make up water, including carbonates, grease and oils.
Pipe scale remotion • A pipe segment was removed from process pipeline for its inspection after a month of CMT Treatment. • Scale remotion is observed inside the pipe, even thou the pH in the system was alkaline and no other chemical was added.

Defects elimination • The previous chemical water treatment was causing economic lost due to steel defects that ascended to several thousand dollars per day. • With the CMT water treatment, the lost was reduce to 90 % in the first two weeks, there after no rejections was found due to the quality of the water.
Conclusions • Make up water volume was reduced to the required to compensate the evaporation lost only as a precaution, in spite that APM’s laboratory demonstrated that the water functionality, allows the cooling tower to operate at higher concentration cycles not affecting the steel quality.
INHIBATION SCALING IN THE “ING.
ANTONIO M. AMOR” OIL REFINERY
Located in Salamanca, Guanajuato,
México.Scaling problem in pipes • The oil refinery cooling tower systems present a considerable scaling problem inside pipes and the heat exchangers due to silica and calcium contents in water.
Tower condition • The CT-100 Cooling Tower, located in the FCC II plant (Fluid Catalytic Cracking) was monitored for the treatment validation. • This system presented a silica content from 150 to 250 mg/L and total hardness from 250 to 330 mg/L.
CMT treatment • After one month of CMT water treatment application an improvement in the thermal efficiency of FCC II heat exchangers as a result of in line scale remotion.
… a thermal behavior difference is observed (increase in the product temperature loss), starting in July 2 of 2007, as shown in the attached graphs…
